EOTech is great for 2 eye open CQB type stuff, my old depts swat team used them.
I shot it a bunch and liked its performance out to about 150yds.
I always like standard iron sights with some trijicon inserts cause its simple and I think that they're much harder to break.

"Just what makes a pure grappler think he can survive with an experienced striker. Especially if that striker isn't following any particular rule set and is well aware of what the grapplers strategies are".
